C2MS11 — Revisit SAMPLE-RATE

C2MS11-56, already approved, removed MNEMONIC.n.SAMPLE-RATE. In conveying this to the EGS Team, including MAV (NASA) and Ryan Conrad (MITRE) there was concern that we were losing fidelity with the data by only using PUBLISH-RATE to create messages but not having multiple samples at a rate of SAMPLE-RATE.

When we were considering this one, we approached it from the perspective that SAMPLE-RATE and PUBLISH-RATE created a dual-mechanism for when to send the MVAL message. While this is still and issue, there may be a way to allow both desired results in a combined way.

One concern of both the C2MS Team and the EGS Team is in getting too many messages published. This is a clear concern with the SAMPLE-RATE, because of the CRITERIA's indication of "when data should be provided for the mnemonic", including on "Change". In fact, it's likely that CRITERIA is the suspect field basically determining how often to "provide" the data rather than SAMPLE-RATE.

Perhaps we could do the following:

• state in C2MS that the messages will only be produced at the PUBLISH-RATE, but that if SAMPLE-RATE is tighter, then there will be multiple samples in the message.
• Instead of removing SAMPLE-RATE, we remove CRITERIA, so that the SAMPLE rate simply determines how often to sample

Whatever we do, we need to revisit SAMPLE-RATE before finalizing 1.1.
